# Interval vs GymTimer

The clearest difference is ads: Interval at none against GymTimer's shown. Interval also leads on device support (3 vs 1). GymTimer's advantage is update cadence (every 4 days vs every 2 months) and iOS requirement (17.0 vs 26.0). On price and in-app purchases there is nothing between them.

Both are free to download. Interval sells 1 one-off in-app purchase and GymTimer sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Interval ships an update every 2 months, GymTimer every 4 days. The most recent releases landed on October 2, 2026 and October 8, 2026 respectively.
